Product details

The 77311-402-25LF: The 25-position count is less common than 20 or 24 — it fills a specific harness count without needing a dual-row part.

Through-Hole Termination and Board Layout

That mating length gives enough engagement for standard box-style receptacles — confirm the receptacle's pin-cavity depth before committing the BOM. No board locks or retention features — the solder joints carry the mechanical load, so the PCB footprint should include plated through-holes with adequate annular ring for solder fillet strength.

Frequently asked questions

What is the pitch of 77311-402-25LF?
